The Complete Guide to Egress Maps
An egress map is one of the most fundamental safety documents for any building. Whether you manage an office, warehouse, hospital, or school, understanding what an egress map is and how it differs from an evacuation map is essential for compliance with OSHA 29 CFR 1910.36, the International Building Code (IBC), andNFPA 101 Life Safety Code. This guide covers everything you need to know about egress maps and how to create one for your facility.
What "Means of Egress" Really Means
The term "means of egress" is a building code concept defined by the IBC as a continuous and unobstructed path of vertical and horizontal travel from any occupied portion of a building to a public way. It consists of three distinct parts: the exit access (the path leading to an exit), the exit itself (a protected route like a stairwell or exterior door), and the exit discharge (the path from the exit to a public way). An egress map visually documents all three components for a given floor or building. Learn more on our egress maps page.
Why Egress Maps Matter for Safety
During an emergency, people unfamiliar with a building's layout have seconds to find the nearest exit. Egress maps provide critical wayfinding information that can save lives. OSHA requires employers with 10 or more employees to post evacuation route diagrams (which include egress information) under 29 CFR 1910.38. Fire marshals inspect posted maps during annual reviews, and missing or inaccurate egress maps can result in citations, fines, or even building closure orders. See our OSHA evacuation map requirements guide for complete details.
Egress Map vs. Evacuation Map: Which Do You Need?
While the terms are sometimes used interchangeably, egress maps and evacuation maps serve different purposes. Egress maps focus on the physical exit system — routes, widths, distances, and code compliance. They are primarily used by architects, fire protection engineers, and code officials during design review and inspections. Evacuation maps are designed for building occupants and include egress routes plus fire equipment, "YOU ARE HERE" markers, assembly points, and emergency procedures. Most posted maps are evacuation maps that incorporate egress information. Our free evacuation map maker generates maps that satisfy both requirements.
OSHA Egress Requirements (29 CFR 1910.36 & 1910.37)
OSHA's exit route standards establish minimum requirements for egress design and maintenance. 29 CFR 1910.36 covers design and construction — exit routes must be permanent, continuous, and provide a path from any workplace location to an outside area. 29 CFR 1910.37 covers maintenance — routes must remain unobstructed, properly lit, and clearly marked with illuminated exit signs. Our AI automatically applies these standards when generating egress maps. Visit our OSHA 1910.37 exit route guide for in-depth coverage.
IBC Chapter 10 Egress Standards
The International Building Code dedicates an entire chapter to means of egress. Key requirements include occupant load calculations (which determine the number and width of exits), maximum travel distances to exits (200 ft unsprinklered, 250 ft sprinklered for most occupancies), dead-end corridor limits (20 ft unsprinklered, 50 ft sprinklered), minimum corridor width of 44 inches for most occupancies, and exit separation requirements based on building diagonal. Egress maps should document compliance with each of these standards. Check your state-specific requirements for local amendments.
How to Read an Egress Map
An effective egress map uses standardized symbols from NFPA 170 to indicate exits, fire equipment, and routes. Green arrows or lines show the recommended paths from the "YOU ARE HERE" marker to the nearest exits. Exit doors are highlighted, stairwells are marked with directional indicators showing which floors they access, and fire safety equipment is placed along routes. A legend explains all symbols used. The map should be oriented to match the viewer's perspective when posted on a wall. Learn more about proper map design on our evacuation map design guide.
